Abstract: The present invention relates to a snow removing agent storage tank preventing the generation of deposits. In a storage tank in which saltwater or a calcium chloride solution used for road snow removal work in the winter is stored, precipitates are generated after long-period storage, and then, when the precipitates are deposited in the bottom of the storage tank, the precipitates can become solidified and scorched, resulting in a deposition phenomenon. The generation of the precipitates or subsequent deposits thereof can cause a reduction in the concentration of the saltwater or the calcium chloride solution, and, moreover, when the precipitates are deposited on a floor or wall and turned into deposits, there can be difficulty in removing the precipitates, and also, the continuous precipitation can cause a deposition layer to become gradually thicker in the storage tank, which can result in a reduction in the storage capacity of the storage tank. Furthermore, the deposition layer can cause the inner wall of the storage tank to be corroded, which can lead to a lifespan reduction problem. In accordance with the present invention, a rotating water current is generated to the snow removing agent in the storage tank to dissolve precipitates, thereby preventing the generation of deposits.
